XMLTV - Category Mappings


I need a bit of guidance regarding the mapping of EPG entries to Jellyfin XMLTV categories: Under XMLTV EPG, one can add pipe (|) delimited values to group channels into the various categories.

What field in the EPG is being read to map to these categories and is it possible to select a specific field to manage the category mapping e.g. group-title=“ZS - Movies”?

Other than the groups/categories the system is correctly importing the EPG and is able to play most functional channels read from the M3U file.
